About Metro NeuroHealth
Operational expertise for outpatient psychiatry practices—built from real-world experience, not theory.
Built for Psychiatry Practices That Expect More Than Basic Support
Metro NeuroHealth was established to solve a problem that continues to affect outpatient psychiatry practices nationwide:
Operational and revenue cycle breakdowns that limit growth, delay reimbursement, and create unnecessary risk.
While many companies offer billing or credentialing services, few understand how these systems must function together in real-world practice environments.
Our work extends beyond task execution. We focus on how these systems function together to ensure practices are positioned to operate efficiently, remain compliant, and be reimbursed accurately.
Metro NeuroHealth was built differently.
We support outpatient psychiatry practices across the country—including private practices, multi-provider groups, and specialty programs—by aligning the operational systems that determine:
Payer enrollment and credentialing accuracy
Prior authorization and intake workflows
Administrative costs increase without improving performance
Documentation alignment with medical necessity requirements
Billing performance and revenue cycle outcomes
Ongoing provider maintenance and compliance
From Specialty Focus to Full Psychiatry Practice Support
Metro NeuroHealth is widely recognized for its work in interventional psychiatry, especially TMS therapy and Spravato® program development, where payer requirements, authorization workflows, and documentation standards are particularly complex.
Through that work, we developed deep operational expertise in:
- Behavioral health reimbursement systems
- Prior authorization management
- Payer medical policy alignment
- Documentation standards for medical necessity
- Workflow design for specialty services
That experience naturally expanded into supporting outpatient psychiatry practices more broadly.
Today, we work with practices across the full spectrum of behavioral health services—not just specialty programs—helping them build and maintain the systems required for consistent reimbursement and long-term scalability.
What Makes Our Approach Different
Most organizations in this space operate transactionally.
They process claims. They submit applications. They respond to problems after they occur.
Metro NeuroHealth operates differently.
We focus on the system behind the outcome.
Our approach is built on aligning:
01/
Credentialing with legal structure, taxonomy, and payer requirementsy
02/
Authorization workflows with clinical care delivery
03/
Documentation with payer-defined medical necessity
04/
Billing processes with real-world payer behavior
05/
Provider data with ongoing compliance requirements
This is not a collection of services. It is an integrated operational framework.
Because of this, our clients are not simply outsourcing tasks—they are strengthening the infrastructure that determines whether their practice gets paid.
Credentialing must reflect payer-specific medical policies. We align:
- Services with payer coverage guidelines
- Provider types with reimbursable services
- Enrollment with authorization and billing requirements .
Behavioral Health Payer Policy Alignment

This prevents situations where services are technically enrolled—but not reimbursed.
Leadership Backed by Real-World Experience

Psychiatric hospital credentialing and enrollment
Individual provider credentialing
Commercial payer, Medicare, Medicaid enrollment
Payer contracting support and alignment
- Owned and operated multiple TMS therapy clinics
- Worked directly within outpatient psychiatry practice environments
- Led the development of operational systems for credentialing, billing, and authorization workflows
- Supported hundreds of providers and practices across the United States
Her experience provides a perspective that is often missing in this industry.
Rather than approaching credentialing, billing, and operations from a theoretical or vendor-based standpoint, Kim understands how these systems function in practice—where breakdowns occur, and how they must be structured to support both patient care and financial performance.

Rosebell Murigu, MBA — Owner
In May 2025, Metro NeuroHealth was acquired by Rosebell Murigu, MBA, an established leader in medical billing and revenue cycle management.
Rosebell is the owner of Quick Claimers Medical Billing and brings extensive experience in:
Psychiatric hospital credentialing and enrollment
Individual provider credentialing
Commercial payer, Medicare, Medicaid enrollment
Payer contracting support and alignment
- Revenue cycle management across multiple specialties
- Billing operations and financial performance optimization
- Practice support infrastructure and scalability
- Organizational leadership and operational growth
Her background strengthens Metro NeuroHealth’s ability to deliver not only operational alignment but also sustained billing performance and financial oversight.
Together, this leadership structure combines clinical, operational, and revenue cycle expertise, allowing Metro NeuroHealth to support psychiatry practices at a level that extends beyond traditional service providers.
Most firms will address one piece of this.
Very few are structured to take control of all of it.
That is the difference between support and operational oversight.
If your credentialing, billing, provider data, and operations are being handled by different people, systems, or vendors—this is where your revenue is being lost.

Metro NeuroHealth provides support across the full lifecycle of outpatient psychiatry operations, including:
- Credentialing, contracting, and payer enrollment
